Assessment of the Western Arctic Boundary Current
Principal Investigator: Pickart, Robert S.
Licensed Year(s): 2018 2013 2012 2011 2010
Summary: The main objective is to characterize the western Arctic Boundary current (which flows at the edge of the shelf), in order to understand its role in dictating shelf-basin exchange of water and materials and how it impacts the ecosystem of the region, including the occurrence of marine mammals. This project is a collaboration between US and Canadian scientists. The research team are using a comb...

Past climate change and carbon cycle in the Arctic region
Principal Investigator: Takizawa, Takatoshi
Licensed Year(s): 2006
Summary: During the last glacial maximum (LGM), the sea level was lowered by ~125m. After the LGM, the area of Bering, Chukchi, and Beaufort Seas expanded dramatically, in association with the rapid raising of the sea level due to the collapse of the continental glacier, and the nutrient rich Pacific water stream into Chukchi Sea had become stronger than that of during the LGM. The abrupt rise of sea level...

Stratigraphy of coastal barriers and under-ice current measurements at Atkinson Point, Tuktoyaktuk Peninsula, N.W.T.
Principal Investigator: Hequette, Arnaud
Licensed Year(s): 1993
Summary: The Canadian Beaufort Sea coast undergoes rapid changes in formation, including the formation and changes of spits and barrier islands. Climatic change, combined with a rise in sea levels, could result in longer ice-free periods, increased wave action and higher rates of coastal retreat and erosion. By measuring spits and barrier islands, analyzing the make-up of the coastal sediments, and measu...

Beaufort Sea Coastal Zone Processes
Principal Investigator: Solomon, Steven M
Licensed Year(s): 2000 1999 1997 1996 1995 1994 1993 1992
Summary: As part of the Northern Oil and Gas Program (NOGAP), the Geological Survey of Canada will investigate shallow sediment types, sediment content in ice and under-ice water currents in the Canadian Beaufort Sea. This will be done by sampling and surveying using hand-held equipment and current meters (placed under the ice). This study will help to determine the role of ice in transporting sediments ...

SOFAR Technology in the Canadian Arctic
Principal Investigator: Perkin, Ron G.
Licensed Year(s): 1991
Summary: Three drifters, called SOFAR (SOund Fixing and Ranging) floats will be ballasted to sink to 1000m and 500m in the ocean. They will be tracked for a period of one year by four underwater listening stations moored along the 700m depth contour northwest of Amundsen Gulf....

Beaufort Sea Ice Motion Programme - Mesoscale Flow Features Study
Principal Investigator: Melling, Humfrey
Licensed Year(s): 1988 1987
Summary: To deploy 11 drifting buoys to improve description of oceanic flow variations on scales of 5-50 km over the Mackenzie shelf of the southern Beaufort Sea; to investigate the relationship between such variations, seafloor topography and shelf water baroclinicity; to estimate the uncertainty which such fluctuations introduce into deterministic models of pack-ice drift...

Geophysical and Geological Investigations of the Lougheed Island Basin-Cameron Island Rise - Desbarats Strait - MacLean Strait Region of the Arctic Island Channels Using Open Water Leads in the Permanent Sea Ice.
Principal Investigator: MacLean, Brian
Licensed Year(s): 1987
Summary: To provide information on the composition, thickness, and geotechnical properties of the seafloor sediments, as well as the effect of ice or current scouring, or slumping, or other modifying influences....

Licence #5129
Principal Investigator: Syvitski, J.P.
Licensed Year(s): 1985
Summary: (1) To emplace current meter and trap arrays into 50m water depth via helicopter; (2) To site survey deltas to ascertain information On their hydrology and sedimentology processes and Quaternary history; (3) To site survey (re survey) coastal sections to understand their stability and geological history....

Licence #5027
Principal Investigator: Melling, Humfrey
Licensed Year(s): 1985
Summary: To install current meters and tide gauges beneath the sea surface to measure and record flow and sea-level for 12 months; pack ice motion and surface wind will be measured by drifting instruments for two months - to enable the prediction of ice motion several days in advance....

Licence #2728
Principal Investigator: Pounder, E.R.
Licensed Year(s): 1982
Summary: Ocean current readings at various depths and profiles of conductivity - temperature and depth....
